1、运行效果
图1 启动服务端
图2 启动客户端
图3 客户发消息
图4 服务端发消息
图5 客户主动关闭,服务段打印异常详情
2、服务器端源码
服务端和客户端都要添加一下namespace:
using System.Net;
using System.Net.Sockets;
using System.Threading;
源码:
class Program { private static string serverIP = "192.168.3.42";//本机ip地址 private static int serverPort = 8888; private static int bufferSize = 1024; private static int count = 0;//表示对话序号 static void Main(string[] args) { IPAddress ip = IPAddress.Parse(serverIP); IPEndPoint ipe = new IPEndPoint(ip, serverPort); Socket s = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); try { s.Bind(ipe); s.Listen(10); Console.WriteLine("等待连接……"); } catch (Exception ex) { Console.WriteLine(ex); } Thread mainTrd = new Thread(Run); mainTrd.Start(s); } /// <summary> /// 启动服务器的socket。 /// 此处要想修改为多用户连接,对每个新用户都new一个RecMsg线程,并且Dictionary<T1,T2>存储每一对ipe和socket即可 /// </summary> /// <param name="o">传入的socket对象</param> private static void Run(object o) { Socket socket = o as Socket; try { Socket connSocket = socket.Accept(); //客户和服务器连接成功。 Console.WriteLine("{0}成功连接到本机。", connSocket.RemoteEndPoint); //接下来的事情交给会话线程 Thread recTh = new Thread(RecMsg); recTh.Start(connSocket); Thread sendTh = new Thread(SendMsg); sendTh.Start(connSocket); } catch (Exception ex) { Console.WriteLine(ex); throw; } } private static void RecMsg(object o) { Socket connSocket = o as Socket; while (true) { byte[] buffer = new Byte[bufferSize]; try { int length = connSocket.Receive(buffer); byte[] realBuffer = new Byte[length]; Array.Copy(buffer, 0, realBuffer, 0, length); string str = System.Text.Encoding.Default.GetString(realBuffer); Console.Write("[{0}] ", count++); Console.WriteLine("{0}说:{1}.", connSocket.RemoteEndPoint, str); } catch (Exception ex) { Console.WriteLine(ex); Console.ReadKey(); break; } } } private static void SendMsg(object o) { Socket connSocket = o as Socket; while (true) { string str = Console.ReadLine(); if (str != string.Empty) { byte[] buffer = Encoding.Default.GetBytes(str); connSocket.Send(buffer, buffer.Length, SocketFlags.None); } } } }
3、客户端源码
class Program { private static string host = "192.168.3.42"; private static int port = 8888; private static int bufferSize = 1024; static IPAddress ip = IPAddress.Parse(host); static IPEndPoint ipe = new IPEndPoint(ip, port); private static int count = 0;//表示对话序号 static void Main(string[] args) { Socket s = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); try { s.Connect(ipe); Console.WriteLine("成功连接到{0}。", s.RemoteEndPoint); Console.WriteLine("请输入要发送给服务器的话,按Enter发送。"); } catch (Exception ex) { Debug.WriteLine(ex); throw; } Thread clientTh = new Thread(SendToServer); clientTh.Start(s); Thread recTh = new Thread(RecMsg); recTh.Start(s); } private static void RecMsg(object o) { Socket connSocket = o as Socket; while (true) { byte[] buffer = new Byte[bufferSize]; try { int length = connSocket.Receive(buffer); byte[] realBuffer = new Byte[length]; Array.Copy(buffer, 0, realBuffer, 0, length); string str = System.Text.Encoding.Default.GetString(realBuffer); Console.Write("[{0}] ", count++); Console.WriteLine("{0}说:{1}.", connSocket.RemoteEndPoint, str); } catch (Exception ex) { Console.WriteLine(ex); Console.ReadKey(); break; } } } private static void SendToServer(object o) { Socket socket = o as Socket; while (true) { try { string str = Console.ReadLine(); if (str != string.Empty) { byte[] bt = Encoding.Default.GetBytes(str); socket.Send(bt, bt.Length, 0); } } catch (Exception ex) { Console.WriteLine("发送失败。"); Debug.WriteLine(ex); throw; } } } }
